The compound 2 was refluxed with various acetophenones and benzaldehydes to produce Schiff’s bases 4a-e and 6a-e. The reaction of these Schiff’s bases with acetic anhydride and phosphorous oxychloride to give benzothiophene linked 2, 5-disubstituted-1,3,4-oxadiazoles 5a-e and 7a-e. The compound 2 was directly cyclized by refluxing with phosphorus oxychloride to give benzothiophene substituted oxadiazoles 3a-e. All the newly synthesized compounds were screened for their antimicrobial activity and were characterized by elemental analyses, IR, 1H NMR and mass spectral data.
